Does anyone remember the Google glasses?

You know the glasses invented by Google which had screens on the lenses, a camera, a microphone so the glasses would answer to orders by vocal commands.
Well, after a long period of advertising during which all websites would say it would be the future… it disappeared.

Why?

Some hints of explanation here:
“The users who didn’t realize that it was rude to wear these info-glasses must have found out soon enough when they’d hear complaints from people on the street, or worse, the ultra-expense Glass was grabbed off their face. I simply wouldn’t talk to anyone wearing Google Glass until they took them off. There was nothing confidential or personal that could be discussed with anyone wearing the device. You’d be foolish not to assume the conversation was being recorded. You may as well pull out an HD video camera and start recording when you were chatting. It was an imposition.”http://uk.pcmag.com/wearable-tech/36416/opinion/rest-in-peace-google-glass-2012-2014
